No. Actually, I used Hysol 9462 on the torrefied top and Old Brown Glue (OBG) on the practice top. I'm still undecided whether to use the Old Brown Glue for the braces on the torrefied top. I know that Ovation probably originally used some sort of epoxy for the braces, and I know that 9462 has good acoustic properties and it'll never come loose, save a really hard hit on the top. OTOH, the OBG will also have excellent acoustic properties, but in a super-humid environment the braces might loosen. The only unknown is how well the OBG grabs onto the torrefied wood. I have some scrap I'm going to use as a test. Decisions, decisions... | ||

Thanks! Yeah, I'm dying to hear how this one will sound when it's done. I might have to hang onto this for a while to make sure it's good enough to send back to Jay. (LOL! Just kidding, Jay!) | ||

The final top is leaving the sander. Although the platter did put a taper into the wood, the taper wasn't as sharp as I'd hoped. The belt that carries the parts through the sander is rubber. I figure that the pressure rollers were compressing the belt causing the angled platter to more or less level itself out. The wood still has a taper, but instead of it being a .030" taper, it's more like .020". In any event, the wood is sanded down and progress continues. And, cut out. Looking good. Bridge alignment holes have been measured, marked and drilled. And, the positioning and alignment have been verified. Tonight, I'll mark the position of the braces and the fiberglass reinforcement strip and get the strip laid down so that I can start laying down the braces tomorrow.

Joined: January 2009 Posts: 1249 Location: Texas | Pretty amazing how the warmth in color of both tops is so close. Dan, do you think that all the additional bracing they threw on it, to address the cracking, had an adverse affect on the resonance? Edited by jay 2015-08-14 11:45 PM | ||

Dan, do you think that all the additional bracing they threw on it, to address the cracking, had an adverse affect on the resonance? Yeah, they are pretty close in color. I'm sure it had some effect, but probably not that much. I've got two similar bars across the lower X-brace in my 1619 and there's no shortage of resonance. Interesting fact. As wood ages, it gets more opaque. Here's some photos. First, a bright light shining through the top made from new spruce. And a bright LED flashlight. Next is the original 1967 top. Finally, the torrefied top. Completely opaque. What this means is that torrefied wood is the holy grail of counterfeit musical instruments. One of the ways that they check for counterfeit violins is to shine a light through the top and if they can see it, then they know that it's a fake. Well, that is, until torrefied tone wood became available. You can fake the look of old wood, but you can't fake the opacity. That's my useless bit of trivia for today. I got the braces laid down today. Y`all should know the drill by now. Visqueen taped to the go-bar deck, apply glue to the braces, then use the go-bars to clamp them into place. | ||

And, after sanding. I made sure to add a couple of reinforcement patches so that if Jay ever decides to add a strap button, he can do so without fear of the plug popping out. Here's a molly I got from JB at the MS. This is what's used to mount virtually all strap buttons on Ovation guitars, and it would be my first choice if I were to add a strap button to the bottom of 485.

Joined: June 2012 Posts: 2316 Location: Pueblo West, CO | I finished designing the label going inside. The typeface is Arabian Normal, which is the same typeface used by Ovation. And, here's the finished label inside the guitar. Here's what it'll look like through the sound hole. Of course, now Jay needs to make a couple of decisions before I glue it into place. My inclination is to stick it down so it's even with the existing label. Otherwise it will look funny, and I don't mean in a humorous way. Edited by DanSavage 2015-08-22 6:13 PM | ||

Whomever stuck that label down in 67, needs to remain that guy. We're not going to take that away from him. "stick it down so it's even with the existing label"
